[ https://issues.apache.org/jira/browse/DISPATCH-382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15726628#comment-15726628 ]
Ganesh Murthy commented on DISPATCH-382:
----------------------------------------
Can you please test this again with the latest code from dispatch master branch and let me know if you still see the crash? If yes, can you please post the backtrace from the crash and steps on how you reproduced it.

> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Routing Engine
> Affects Versions: 0.6.0
> Environment: Debian 8.3, Apache Qpid Proton 0.13.0-RC for drivers and dependencies, Hardware: 2 CPUs, 15 GB RAM, 60 GB HDD each on 3 separate machines
> Reporter: Vishal Sharda
> Priority: Blocker

> Network: A network of 3 interior routers built from trunk and connected to each other using 2-way SSL.
> We ran a Proton-J Reactor API based client to start 50 receivers and 0 senders on one of the above 3 routers. After that we ran "qdstat -c". This leads to intermittent crash in the router. This crash could not be reproduced while running the routers independently or inside gdb. When we run the routers inside Valgrind, this crash is frequent. I was able to reproduce the crash 3 times using Valgrind (Screenshots and Valgrind output files are attached).
> This intermittent crash becomes permanent in our instrumented build.
